WORK-HOLDER FOR SHAPERS.

Application filed September 1, 1911.

ments in lVork-l-Iolders for Shapers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in work holders for shapers andmore particularly to such holders which are adjustable for tapered workand its object is to provide the same with improved means for holdingthe work; improved means for adjusting the holder; improved means forsupporting the holder against the action of the tool; and to provide thesame with various new and useful features hereinafter more fullydescribed and particularly pointed out in the claims, reference beinghad to the accompanying drawings, in which Figure l is a side elevationof a device embodying my invention applied to a draw out shaper; Fig. 2a front elevation of the same; Fig. 3 a plan view of the same; Fig. 4 atransverse section on the line H of Fig. 1; Fig. 5 a detail in plan viewof the support for the holder somewhat enlarged and with portions brokenaway; and Fig. 6 a transverse section of the same on the line 6--6 ofFig. 5.

, Like numbers refer to like parts in all of the figures.

1 represents the vertically and horizontally adjustable bed of theshaper on which the work is usually secured. 2 the reciprocating toolcarrier of the shaper. 3 the cutting tool of the same. 4 the body of thework holder. This body is provided with lugs 6 near the middle pivotedupon a bolt 5 extending through a base plate 5 detachably secured to thebed of the shaper. The body is adjustable about the axis of the bolt 5by means of downwardly extended arms near the rear embracing the baseplate and having segmental slots 6 and a binding bolt 7 extends throughthe slots and through the base plate 5*.

8 is an adjusting screw engaging one of the arms to accurately adjustthe inclination of the body 4;.

Specification of Letters Patent.

Patented July 30, 1912.

Serial No. 647,150.

9 is a fixed index and 10 a scale on the body to indicate the angle ofadjustment.

The body 4 is divided into two substantially equal channels to receivethe work by means of a middle partition and in each channel is alaterally movable clamping bar 12 between which and the partition 11 thework is clamped by means of screws 14 engaging the said bar. The bar isalso further secured in place by bolts 13 extending through transverseslots in the bottom of the body and into the bar 12.

15 represents supporting blocks used in connection with certain forms ofwork such as railroad rails when shaping the same for split switches,

To su sport the holder against the force exerted y the cutter 3, Iprovide a vertically adjustable bracket 16 mounted on the frame of theshaper provided with slotted arms 17, vertically adjusted by a screw 19and held in adjustment by binding screws 25 extending through said slotsand into the frame of the shaper. On this bracket is slidably mounted agrooved wedge 20 embracing the edge of the bracket 16 and slidablethereon. This wedge is secured in adjustment by bolts 22 extendingthrough the grooved portion thereof and adjustable in recesses 23 insaid bracket. Slidably mounted on the wedge 20 is a facing strip 21which engages the rounded rear side of a buffer bar 24 fixed on the rearof the body 4;. By means of this wedge the device may be accuratelyadjusted to rigidly support the rear end of the holder against the forceexerted by the cutter.

I am thus able to produce a very strong and substantial holder which maybe accurately adjusted, and will withstand heavy cutting strains. Itwill also be noted that the holder is double and adapted to hold twopieces of work side by side so that while cutting one piece another maybe adjusted and secured in place and the bed 1 shifted to alternatelyoperate upon the respective pieces of work, thus saving time andoperating the machine practically continuously.

What I claim is 1. A work holder for shapers, comprising a bodypivotally mounted on the bed of the shaper, means for adjusting saidbody at more or less inclination to the stroke of the cutting tool ofthe shaper, a bracket vertically adjustable on the frame of the shaperopposite the inner end of said body, a Wedge slidable on the bracket, afacing strip slidable on the Wedge, and bolts to secure the Wedge inplace 'on the bracket.

2. A Work holder for shapers, comprising a body pivotally supported onthe bed of the shaper, means for adjusting the body at va- 1 riousinclinations to the stroke of the cutting tool of the shaper, a bufferbar having a rounded surface attached to the rear of the body, avertically adjustable bracket mounted on the frame of the shaperopposite said bar, a Wedge slidably mounted on the bracket, and a facingstrip slidable on the Wedge engaging the buffer bar,

3. A Workholder for shapers, comprising a body pivotally mounted on thebed of the shaper, means for adjusting said body at various inclinationsto the stroke of the cutting tool of the shaper, a bracket verticallyadjustable on the frame of the shaper and opposite the said body, aWedge having a groove to receive the edge of'the bracket, said edge alsohaving elongated recesses therein, bolts in the Wedge extending throughthe groove and recesses and adjustable in the latter, a facing strip onthe Wedge slidably connected thereto by tongue and groove adapted toengage the rear of the Work holder and support the same against thestroke of the cutter.

t. A Work holder for shapers, comprising a base plate detachably mountedon the bed of a shaper, a body pivoted near the front of said plate,arms on said body embracing the plate and having segmental slotsconcentric With the aXis of the pivot, bolts extending through saidslots and clamping the arms to the plate, a bracket verticallyadjustable on the frame of the shaper, a Wedge adjustable on thebracket, a facing strip adjustable on the Wedge and a buffer bar on saidbody engaged by said facing strip.

In testimony whereof I affix my signature in the presence of tWoWitnesses.
